Question

Show transcribed image textFor a complex exponential signal x(t) = 2ej2 pi t: Determine its analog frequency Ohm 0 in rad/sec and its analog frequency f in hertz. Then find the signal's period. Suppose y(t) = ej pi t. Would the sum of these signals z(t) = x(t) + y(t) also be periodic? If so, what is the period of z(t)? Suppose we then generate a signal v(t) = x(t)y(t), with the x(t) and y(t) signals given before. Is v(t) periodic? If so, what is its period?
